Static pie linked no config file version

Release without a config file, static pie linked, much smaller than it was!

Stable uring

Compiles on stable, uses io-uring for io and events.

Smaller, unsafer, rustier.

Goes no_std and no libc, now requires nightly to build. Also some minor fixes.

Safer, smaller, better

This version rewrites the back end socket interface logic, makes configuration a bit more forgiving, and fixes some bugs due to spec-compliance issues in focus-handling.
